A small river pebble sand making machine is a kind of equipment specifically designed to crush river pebbles into artificial sand. As technology continues to advance and equipment requirements become increasingly stringent, these machines have undergone several generations of upgrades, resulting in a wide variety of types. So what are the specific types? Here we recommend a few suitable models for you.
Main Types of Small Pebble Sand Making Machines
1. Roller Crusher Sand Making Machine
The double roller crusher is one of the most popular choices for small-scale pebble sand production. It works by using two counter-rotating rollers to squeeze and shear the pebbles until they break into sand-sized particles.
Common small models include:
2PG610×400 – capacity 3–9 t/h, feed size<36mm
2PG750×500 – capacity 3–16 t/h, feed size <40mm
2PG750×700 – capacity 5–25 t/h, feed size <40mm
Advantages:
Simple structure, easy to maintain;
Low operating costs and long service life;
Good for high-hardness materials like pebbles;
Adjustable output size (usually 2–10mm);
Low dust and noise thanks to sealed design.
2. VSI (Vertical Shaft Impact Crusher) Sand Making Machine
The VSI sand making machine, also known as an impact sand making machine, is the most advanced equipment for artificial sand production. It has stone beat stone and stone beat iron two work methods. Luoyang Dahua PLS 550sand making machine and PFL-750Ⅲ compound crusher are recommended for small pebble sand making production.
Advantages:
Produces high-quality sand with excellent grain shape (cubical particles)
Good for very hard materials like pebbles, granite, and basalt;
Has shaping function—improves particle shape;
Adjustable output size down to 0–5mm.
3. Fine Jaw Crusher (DHKS Series)
The fine jaw crusher is often used as a pre-crushing step before the main sand making machine. It breaks larger pebbles (210–320mm) down to 18–90mm, which then feeds into the sand making machine.
How to Choose the Right Machine
Step 1: Determine Required Output
Start by calculating how much sand you need per hour. Small machines typically range from 5 to 20 tons per hour.
Choosing a machine that’s too large will waste electricity and increase your initial investment.
Step 2: Consider Budget
Higher budget, better quality: A VSI sand making machine produces superior sand but costs significantly more.
Step 3: Check Feed Size
Make sure your pebbles are the right size for the machine you choose.
Most small roller crushers accept feed sizes up to 30–40mm
If your pebbles are larger, you’ll need a jaw crusher as a pre-treatment step
Step 4: Evaluate Maintenance and Operating Costs
Pebbles are highly abrasive, so wear and tear is a real concern.
Roller crushers have lower maintenance costs and longer roller life, especially if you choose models with high-chromium alloy rollers.
VSI machines have higher wear part replacement costs but produce better sand.
